• The favorite: Tomsula. The in-house candidate has been the favorite since the job opened. York and Baalke are reportedly hold him in high regard and both love his loyalty to the 49ers. San Francisco even blocked the Washington Redskins from interviewing Tomsula and Fangio. That’s telling, no?

• The dark horse: Shanahan. A former San Francisco offensive coordinator, the vet has the requisite Super Bowl wins on his resume (two). The drawback is Shanahan being a proponent of the zone-blocking scheme. That would be departure from the 49ers power-blocking schemes. 49ers brass are slated to interview his son Kyle Shanahan (current Cleveland Browns offensive coordinator) as well. For what position (head coach or OC) is unknown.

• Who should get the job: Ryan. He may be brash and rub people the wrong way, but no one can deny Sexy Rexy’s defensive prowess. His Jets teams never finished below the Top 10 in overall defense during his tenure in New York. But, there are reports York and Gamble want a coach who won’t rock the boat. That’s not Ryan’s forte.

• The favorite: Del Rio. Although a recent options (Raiders requested and received permission Friday), Oakland reportedly few a contingent to Denver Saturday to speak with the Bay Area native in advance of the Broncos’ playoff game. Del Rio wants the job. Who else can honestly say that?

• The dark horse: Sparano. He’s supposedly the head coach if no one else wants the gig (not really a sparkling endorsement). While he did an admirable job getting the Raiders to three wins, his lack of fortitude (punting on 4th and short with nothing to lose) and foresight (not starting running back Latavius Murray sooner) make him an inspiring hire.

• Who should get the job: Del Rio. If Davis feels burned by hiring another coordinator who has zero head coaching experience (cough, Dennis Allen), Del Rio is the Raiders’ man. He oversees a dominant defense in Denver and also led the Jacksonville Jaguars to the playoffs — twice.
